Application filed August 30, 1911. Serial No. 646,376.

securing means or bracket for attaching the same to the vehicle frame,

While I am aware that there are several styles of buffers in use for this purpose, they depend upon being bolted or riveted to the vehicle frame, thus requiring that the frame be drilled and some of the bolts replaced,

and requiring considerable time to attach the buffer and at considerable expense.

The object of the present invention is to produce a device of this class thatshall be cheap, durable, efficient, and contains few parts, and be readily and quickly attached without alteration to the vehicle frame.

Another object of the invention is to provide means whereby the buffer may be adjusted to receive the shock of collision in a horizontal line with respect to the machine to which it is applied.

With these and other objects in view, my invention consists in certain construction and combination of parts as will hereinafter be fully described and claimed in the annexed specification, and, illustrated in the accompanying drawings which form a part of this application, and in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my invention as shown, thatI do not confine myself to the exact design, as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention.

In the drawings:--l igure 1, is a top plan view in detail showing the device as applied to an automobile frame. Fig. 2, is a side elevation of the attaching mechanism as socured to the frame of the vehicle. Fig. 3, is a front elevation of the same. Fig. 1, is a vertical sectional view, taken on the line X--X of Fig. 1.

Referring to the drawings: the forward portions of the vehicle frame are indicated reception of an adjustment bolt 13.

by the numeral 1, and are secured to the semr-elliptic spring 2, by the bolt 3..

The buffer bar 4, is of the usual design, and has secured thereto the fittings 5, which are hollow and provided with an open end and a longitudinal elongated slot 6, extendmg through their lower surface. said fittings 5, are slidably mounted a plunger 7 which is retained therein by a set screw 8, threaded into said plunger 7, and extending through said slot 6, thus limiting the sliding movement of said plunger 7, within the fitting or sleeve 5. i is formed upon its other end with a head 23, and on said plunger with one of its ends in contact with the head 23, and the other end in contact with the end of the fitting 5 15 mounted animpact cushion spring 24. Said head 23, has a curved surface 9, adapted to rest against the bolt eye 10, of the frame l, and an upwardly and rearwardly extending adjustment lug 11, which lies upon the upper surface of the frame 1, and which is provided with an elongated transverse slot 12, in the body thereof for the Secured thereto in an adjustable manner by said bolt 13, is the adjustment block 14, which is formed with a lower surface of approximately the same curve as the curve of the frame 1, and a corrugated upper surface 15, and a forwardly extending lug 16, provided with a transverse hole in the body thereof for the reception of the bolt 13; and in this manner, the plunger may be adjusted or set to extend in a horizontal direction with respect to the vehicle frame.

For securing the device to the vehicle frame 1, without dir lxlling any holes .or disturbing the same, I lave provided a novel clamp capable of adjustment for different sizes and shapes of frames, which comprises a bolt 17, resting in one of the corrugations 15, and which is threaded upon both ends and provided with the nuts 18 while secured thereon by said nuts 18, are the side plates 19, which extend downward past the sides of the frame 1, and which are pro Within For further strengthening the device and to revent any upward movement of the bu er-bar, there is provided a U-clamp 25, secured to the spring 2, near the pivot end thereof; said clamp being connected to the head 23, by a link 26, held in place by the cap screws 27, and 28, in such a manner that said link 26, has a slight movement buffer bar at right angles thereto, a plunger mounted in said socket fitting, a head formed on said plunger adapted to engage the end of the vehicle frame, an impact spring mounted on said plunger between its head and said fitting, a slotted lug formed on the head of said plunger, a block adapted to be adjustably mounted to the head of said plunger, said block formed with a corrugated upper surface and an adjustable clamping means for securing said block to the vehicle frame.

In testimony whereof I afiix my signature in presence of two witnesses;

OSCAR F BRINKMAN.
